Class PingServer

Takes requests for sonar pings from a network socket, and then returns
VRML representations of both sonar ping and any target detections made.

Since calculation of numerous ray trajectories is extremely computation intensive,
rendering and ray tracing often need to be performed on separate computers
in order to improve performance times. PingServer provides a network interface between
the ray-tracing computational methods and the VRML-based 3D rendering methods.
